The present invention relates to a spacer fabric with advanced cushionability, flexibility, and thermal conductivity, and a method of fabricating the same. In accordance with the present invention, the spacer fabric is useful as a car seat fabric. In particular, the spacer fabric is applicable to a car seat equipped with an actuator and a heating/cooling apparatus inside, due to the advanced flexibility for transferring the actuator moving effect to the body, the increased cushionability for minimizing the hardness of the surface of the device, and the high thermal conductivity for effectively transferring the quick heating/cooling effect to the body.

What is claimed is: 1. A spacer fabric with advanced flexibility, cushionability, and thermal conductivity, comprising a top layer and a bottom layer formed by knitting Latent Self Crimping Yarn (LSCY) and Draw Textured Yarn (DTY), and multiple pile yarns formed between the top and bottom layers linking the two layers, wherein: the LSCY is a side-by-side yarn containing one component or the combination of two components selected from the group consisting of polyethyleneterephthalate (PET), polytrimethyleneterephthalate (PTT), polybutyleneterephthalate (PBT), and nylon; the DTY is prepared by drawing polyester or nylon filament yarn; the LSCY and DTY have a diameter of 75 to 400 Denier; and the pile yarn is a monofilament made of a component selected from the group consisting of polyester, nylon, acryl, metallic yarns, and carbon fibers, and having a diameter of 20 to 50 Denier. 2. The spacer fabric according to claim 1, wherein the LSCY is a side-by-side yarn prepared by conjugated spinning wherein PET is used as a sole component and an orientation restrainer is mixed with only one side of the yarn, or wherein two components having different peculiar viscosity and shrinkage are used. 3. The spacer fabric according to claim 1, wherein the DTY is prepared by drawing polyester pre-oriented yarn (POY), double twisting two or more folds of the obtained drawn yarn at the twist ratio of 10 Z to 50 Z, first heating the twisted yarn at 180 to 200° C., and second heating the first heated yarn at 190 to 210° C. 4. The spacer fabric according to claim 1, wherein the top layer or both of the top and bottom layers have holes with an average hole diameter of 3 to 5 mm and the ratio of machine direction (MD)/across machine direction (AMD) is 1 to 1.5. 5. The spacer fabric according to claim 1, wherein the pile yarn has a semi-cross structure that is knitted by moving 1 wale. 6. The spacer fabric according to claim 5, wherein the pile has a pile structure forming coordinates of 2100112 and 01122110. 7. The spacer fabric according to claim 1, wherein the thickness is 7 to 9 mm. 8. The spacer fabric according to claim 1, wherein the weight ratio between the LSCY and the DTY is 1:0.75 to 2 (LSCY weight:DTY weight). 9. The spacer fabric according to claim 1, wherein the weight ratio between the LSCY, the DTY and the pile yarns is 1:0.75 to 2:0.5 to 1.5 (LSCY weight:DTY weigh:pile yarn weight). 10. A method of preparing a spacer fabric as defined in claim 1, comprising: forming a top layer and a bottom layer by knitting Latent Self Crimping Yarn (LSCY) and Draw Textured Yarn (DTY), wherein the LSCY is a side-by-side yarn prepared by conjugated spinning using one or two components selected from the group consisting of polyethyleneterephthalate (PET), polytrimethyleneterephthalate (PTT), polybutyleneterephthalate (PBT), and nylon, and has a diameter of 75 to 400 Denier, and the DTY is prepared by drawing polyester or nylon filament yarn and has a diameter of 75 to 400 Denier; forming multiple pile yarns between the top and bottom layers linking the two layers, wherein the pile yarn is a monofilament made of a component selected from the group consisting of polyester, nylon, acryl, metallic yarns, and carbon fibers, and having a diameter of 20 to 50 Denier; and performing finishing steps comprising a stabilizing step, a pre-setting step, a dyeing step, a final setting step, and a resin treatment step. 11. The method according to claim 10, wherein the LSCY is a side-by-side yarn prepared by conjugated spinning wherein PET is used as a sole component and an orientation restrainer is mixed with only one side of the yarn, or wherein two components having different peculiar viscosity and shrinkage are used. 12. The method according to claim 10, wherein the DTY is prepared by drawing polyester pre-oriented yarn (POY), double twisting two or more folds of the obtained drawn yarn at the twist ratio of 10 Z to 50 Z, first heating the twisted yarn at 180 to 200° C., and second heating the first heated yarn at 190 to 210° C. 13. The method according to claim 10, wherein the top layer or both of the top and bottom layers have holes with an average hole diameter of 3 to 5 mm and the ratio of machine direction (MD)/across machine direction (AMD) is 1 to 1.5. 14. The method according to claim 10, wherein the pile yarn has a semi-cross structure that is knitted by moving 1 wale. 15. The method according to claim 14, wherein the pile has a pile structure forming coordinates of 21100112 and 01122110. 16. The method according to claim 10, wherein the M/C plate distance is 7 to 9 mm when forming the top and bottom layers. 17. The method according to claim 10, wherein the weight ratio between the LSCY and the DTY is 1:0.75 to 2 (LSCY weight:DTY weight). 18. The method according to claim 10, wherein the weight ratio between the LSCY, the DTY and the pile yarns is 1:0.75 to 2:0.5 to 1.5 (LSCY weight:DTY weight:pile yarn weight). 19. The method according to claim 10, wherein the stabilization step is performed under the conditions of a reaction temperature of 100 to 140° C., an enlargement rate of 15 to 25 m/min, and a fabric width enlargement of 5 to 10 %. 20.
